Problems solved by technology

The traditional one-way tension line device can only realize the horizontal displacement measurement and the static level device can only realize the vertical displacement measurement, and the respective measurement ranges are greatly limited, which also increases the cost
In addition, when the one-way tension wire is in use, as time goes by, the liquid in the water box will naturally lose, resulting in inaccurate measurement, and the liquid will also corrode the tension wire for a long time. cannot be measured accurately

Embodiment 1

[0025] Such as figure 1 In the shown two-way tension line end device, the tension line body (3) is introduced from the fixed end (1), the end point is provided with a fixed fixture (8) clamping device (that is, the fixed end), and the other end is provided with a load device Promptly hang heavy end (2), be provided with line body reel (9) wheel shaft simultaneously, the steamboat of wheel shaft constitutes indium steel wire reel, fixed end (1), hang heavy end (2) both coaxial. 60kg--80kg weight is hung on the lower end of the load wheel as a preload. The measurement range of each measuring point where the sensor is installed is ±50mm horizontally, ±25mm vertically, and the accuracy is ±0.1--±0.2mm. There is a manual measuring ruler installed in the measuring point box, which can check the reliability of the measured value of the automation system. Its technical performance characteristics are as follows:

[0026] 1. The system still uses the tension line body as the carrier ...

Embodiment 2

[0041] Such as figure 2 The two-way extension line measuring points shown are the same as the four observation points introduced by the indium steel wire at the dam end. They are respectively introduced into the two-way measuring point box by their respective signal lines, and the measuring point box is led into the observation room through the signal line. The working principle is the same as the embodiment.

Abstract

The invention discloses a two-way bracing wire device, which belongs to a measuring device in water conservation, communication and rock and soil field. It includes a fixing end, suspending end, bracing wire body, two-way measuring box, automatic water filling device, liquid storage barrel and connecting pipe, the two-way measuring box has a water box, floating bracket, manual measuring meter and two-way bracing wire device; the water box, liquid storage barrel and the automatic liquid filling device are connected together through the connecting pipe, the bracing wire is leaded in through the fixed end to the suspending end through each measuring bracket, and the wire are winded on the heavy wheel. The invention changes the single measuring aim of the single way bracing wire device and static force level device, realizes two functions with one wire.

Description

technical field [0001] The invention relates to a device for measuring displacement of a dam, more precisely, the invention relates to a device for measuring a dam by using tension wires, and belongs to the technical field of measuring devices in the fields of water conservancy, transportation, and rock and soil. Background technique [0002] With the development of science and technology, higher requirements are put forward for the dam prototype observation instruments. In addition to using the manual observation steel ruler to obtain the original data, it should also be able to realize automatic monitoring, so that the engineering management department can grasp the safety status of the project in time and make corresponding measures. This is also the direction of development of engineering safety monitoring instruments. The traditional one-way tension line device can only realize the horizontal displacement measurement and the static level device can only realize the vert...
